The Ego and the Uncanny Double
Freud mentions (as stated by Otto Rank) that "the 'double' was originally an insurance against destruction to the ego, and 'energetic denial of the power of death'" (9). Nelson is the mastermind behind the experiment, and claims to experiment with death because religion and biology failed in that department. Nelson also wants to be well known as the person who found the key to death, and share what everyone will experience. Nelson also wants to see if he can find the answer to extending human is through death.
